Abstract: The various embodiments of the present invention disclose a method and system for performing Hybrid Repeat Request (HARQ) in cellular operations over unlicensed bands. The method comprises of checking, by an eNodeB (eNB), whether an unlicensed channel is occupied by a User Equipment (UE), initiating transmission of Redundancy Versions (RVs) corresponding to a HARQ process on the unlicensed channel if the unlicensed channel is occupied by the UE, verifying if a channel occupancy period is over and an acknowledgement for the HARQ process is received from the unlicensed channel and initiating a Redundancy Version (RV) bundling for retransmission of the bundled RVs without awaiting an acknowledgment for the HARQ process from the unlicensed channel, if the channel occupancy period is not over.

Abstract: The present invention provides a method and system for performing Hybrid Automatic Repeat Request (HARQ) operation in an asymmetric multicarrier communication network environment. In one embodiment, a method includes receiving resource allocation information from a base station. The method also includes transmitting the HARQ packet to the base station in a transmit time interval (TTI) corresponding a first or second partition of an uplink allocation interval on a second carrier. The method further includes receiving HARQ feedback information corresponding to a previous HARQ packet transmission. Furthermore, the method includes determining a TTI in a subsequent uplink allocation interval based on the partition of the uplink allocation interval in which the HARQ packet is transmitted if the HARQ feedback information indicates negative acknowledgement. Moreover, the method includes transmitting the HARQ packet to the base station in the determined transmit time interval of the subsequent uplink allocation interval on the second carrier.

Abstract: A method and system for acquiring mmWave carrier in a wireless communication network is disclosed. In one embodiment, an MS acquires a low frequency carrier and then acquires the high frequency carrier. Since the low frequency carrier and the high frequency carrier are transmitted by same BS, the BS provides assistance information on the acquired low frequency carrier to the MS to acquire a synchronization signal which is transmitted on a high frequency carrier using beamforming. The assistance information includes synchronization signal beam time slots, synchronization signal beams which the MS needs to search, beam ID and so on. Based on the assistance information, the MS monitors the high frequency carrier to search and acquire the synchronization beam signal transmitted on the high frequency carrier. The MS determines the beam ID of the received synchronization beam signal and reports to the BS on the low frequency carrier.
